Power Rankings Fluctuation

Power Rankings are a fickle thing. They truly are meaningless, well except for college football, and yet everyone seems to do them. Who's better than who is always on everyones mind so the best way to say who's better than who is to print out a 32 deep list.But then when putting together the list two things make them completely biased. First off, everyone needs expectations and preseason rankings are those biases. So the Falcons for instance started out as the worst team in the NFL and yet wound up at 7 to end the season. Whoops. The next bias is that whatever happened today is significantly more important than what happened yesterday. Look at the Jets. They get crushed on National TV in San Diego and move to #21 on the list aka pathetic then they lose to the Raiders to stay below the midway point yet weeks later when they beat the Titans they are the 3rd best team in the NFL? Whoops.Anyway here is your ESPN NFL Power Rankings. I've including graphs tracking the progress...
